PULLEY.

Specification of Letters Patent.

Patented Get. 4, 1921.

Application filed August 23, 1920. Serial No. 405,383.

To all whom it may concern:

Be it known that I, CHARLES A. STONER, acitizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented new and useful Improvements in Pulleys, of which the followinis a specification.

This invention relates to improvements 1n blocks or pulleys and theprincipal object of the invention is to provide a casing for inclosingthe pulley or sheaves of the block so as to prevent injury to thepersons using the same by having their fingers or handscaught betweenthe cables and wheels.

Another object of the invention is to provide the casing with openingsthrough wh ch the cables may pass and to make the casing of two partswhich are detachably held together so that access can be had to theparts when desired.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to' behereinafter fully described, illus trated in the accompanying drawingsand specifically pointed out in the appendeo claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is an edge view of the improved device.

Fig. 2 is a longitudinal sectional view.

Fig. 3 is a view of the two parts of the casing showing the sameseparated.

Fig. 4 is a top view.

In these views A indicates the casing for inclosing the sheaves 1 of theblock or pulley. This casing is made up of the plate 2 and the plate 3,the plate 3 being bent at right angles to provide the top-portion 4:.The

lower ends of the plates 2 and 3 are tapered as shown. The plates areheld in spaced relation by the bolts and nuts 5, the bolt at the lowerend carrying a sleeve 6 to which is attached the hook 7. The shaft 8 forthe sheaves passes through the centers of the plates and has its endsthreaded to receive the nuts. The supporting hook 9 for the device maypass through the centrally arranged hole 10, formed in the top at andthis top is provided with the holes 11 through which the cables maypass. It will thus be seen that the sheaves with the portions of thecables passing over the same are protected by the casing and its boltsso that the danger of a person having his hand caught between the ropesand sheaves is removed.

hen i is desired to remove the casing to get at the sheaves, by removingthe nuts lifting off the plate 3.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claim.

What I claim is A device of the class described comprising a casingformed of two side plates, with the upper portion of one side plate bentover to form a top, said top having openings therein for the passage ofthe cables, bolts holding the side plates in spaced relation, asheavecarrying shaft passing through the side plates, a sleeve carriedby the bolt at the lower end of the plates, a hook carried by saidsleeve and a supporting hook passing through one of the holes in the topand connected with the sheave-carrying shaft.

In testimony whereof I affix my signature.
